Diagnostic Medical Sonography uses reflected sound waves to create images.

Diagnostic Medical Sonography uses reflected sound waves to create images.

• A. Diagnostic Medical Sonography
• B. X-ray radiography
• C. Nuclear medicine
• D. MRI

Answer: (A)

Ultrasound imaging works by sending high-frequency sound waves into the body and listening for echoes that return from tissue interfaces. The transducer both emits and receives these echoes; by measuring the time it takes for echoes to return and their strength, the system constructs a real-time image of soft-tissue structures. Because it relies on reflected sound waves, it does not use ionizing radiation, setting it apart from X-ray radiography (which uses X-rays), nuclear medicine (which uses radiotracers and gamma rays), and MRI (which uses magnetic fields and radiofrequency pulses). This statement describes Diagnostic Medical Sonography precisely.
